Rafael Espindola 96bfb50c03 Write relocations in the end of the file. This matches what gas does and
makes files easier to diff.

Rafael Espindola 9ca41113f6 Make sure .text doesn't produce extra alignment.

Rafael Espindola 75d65b9a03 Move ELF to HasReliableSymbolDifference=true. Also take the opportunity to put
symbols defined in merge sections in independent atoms.

Rafael Espindola cf1f985838 Reapply 114678 and 114667. Reverting them did not fix the bot:

Rafael Espindola f458f04eb1 Correctly handle weak undefined symbols. Before we would get a invalid binding
(2 == STB_WEAK | STB_GLOBAL).

Rafael Espindola 48e108753b Represent relocations against local symbols as relocations against the section
they are in. Both ways should be equivalent, but gas produces relocations
against the section.

Roman wrote the patch, I added the test.

Rafael Espindola 44bf266111 Print the address of sections as 0 and create the metadata sections in the
same order as gnu as.

Rafael Espindola f667d929ce Add a InitSections method to the streamer interface.
The ELF implementation now creates text, data and bss to match the gnu as
behavior.

The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.

A nice benefit is that -n is not required anymore when producing
ELF files.

Benjamin Kramer 0a96578ac0 Add an elf-dumper utility.
- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

Daniel Dunbar 8e92d9b68d MC/ELF: Allow null values in virtual sections, ELF doesn't use special
directives for putting contents in .bss, for example.
